When it does not arrive, you get an answer

"Why didn't my article arrive?" is the most common question in this category, and the usual answer is a red dot next to the word Failed.

The reason it is usually a red dot is that the failure happens somewhere the service cannot see. The file left. The mail provider accepted it. Then Amazon looked at the sender, found it was not on the approved list, and dropped the document — not with an error code, but with a plain-English email sent back to whichever address the document came from.

We receive that email

The address a document comes from is your address, on our domain. So Amazon's notice lands with us. We read it, work out which of the eight real causes it was — the sender not approved, no such Kindle address, the attachment over the size limit, Amazon's own daily cap, and so on — and turn it into the specific thing you have to do. Usually that is one string to copy and one settings page to open.

What you would actually see

The test page

Because we can read the refusal, we can also provoke it on purpose. Every new Kindle gets a one-page test document before anything real is sent, and the dashboard waits to hear that it arrived. A missing approval turns up in the first minute, not after a week of silence — which is the failure mode that makes people quietly give up on tools like this.

The silent one

There is one case Amazon does not write back about: a document it accepted but never delivered. For those, the dashboard watches the clock. A send that our mail provider accepted and that nothing has confirmed after a day is flagged as sent, awaiting confirmation, with the one check that resolves it — is it in your Kindle library? If not, the sending address is almost certainly missing from the approved list — and it says so.
